Crosshead is manufactured from high quality, cast steel and the guides are manufactured from a quality manganese bronze normally used in bearings. This combination of materials provides a low friction interface and generates very little heat, which indicates no friction, which equates to no wear.
Power end is used to transfer power and convet modes of motion and speed, and provide proper power for hydraulic end assembly, which comprises the frame, pinion shaft, crankshaft, crosshead, crosshead pin, extension rod, crosshead guide, guide tube , stuffing box, etc.
Hydraulic end is used to convert mechanical energy into liquid energy and transport mud, including: valve pot, discharge manifolds, flange bent pipes, discharge five-port, valve assembly, cylinder cover plug, piston, piston rod, cylinder cover plug, cylinder cover flange, liner cage, cylinder cover, valve rod, wear-resistant plate, locking clip, valve rod guide, valve guide retainer, hydraulic pull valve device, etc. There are respectively discharge pulsation chamber, shear pin type relief valve and discharge filter installed at the outlet.
